All these backslashes makes this quite hard to maintain. This is mostly static text, the only dynamic part is name, but I don't think you really need it to be dynamic. You can just make a static readme and load it with file-embed.

[zliu41]

Even if you really want the dynamic name, you can easily do a Text.replace.

I'm not sure if data-files works. @zeme-wana What do you think? You mentioned this before about data-files:

They do in CI. But once the executable is built and deployed to some machine, the files are nowhere to be found

In any case, this is exactly what file-embed is designed to do, and that definitely works.

[zliu41]

Yeah, since we release uplc as a single executable, this can't work. You need to use file-embed.

@zliu41 I'm now getting https://ci.iog.io/build/12767781/nixlog/18 which I'm unable to reproduce locally.

@zeme-wana said that there might be platform specific issues with this approach, so I'm going to just use the original version, which was to embed the file into a Haskell string. It's much simpler, the file isn't that large, we won't have to change it too often and I think we've already spent too much time on this.

platform specific issues

What platform issues - can you elaborate? We use TH to load the cost model JSON files and there's no problem with that.

@zliu41 The message I got from @zeme-wana regarding platform specific issues is that it might break CI on Windows. I did not get to see if this error would happen or not, because I got a different error (https://ci.iog.io/build/12767781/nixlog/18) which I also mentioned in the previous message. I wasn't able to reproduce this error locally, and it seemed to me like, given the issue and other potential issues, we should opt for the simplest solution.

Your error is because you didn't add the md file to extra-source-files.

@zeme-wana this is no longer a problem, which is why we decided to keep readJSONFromFile, right? And file-embed is also much less likely to cause the same problem than readJSONFromFile.
